If the rollout of 4G is any indication, wireless carriers will start making claims about their 5G networks before 5G is even officially available. There will be talk about increased capability for the Internet of Things, including self-driving cars and the ability to watch super high definition video on your tablet, maybe while your car drives itself. But before any of these promises can come to pass, a lot of groundwork must be done, including assigning and selling wireless spectrum for 5G. Some of the lower-frequency spectrum could come very close to the unassigned TV spectrum currently used for the <a href="http://www.oplin.org/4cast/?p=5217" target="_blank">TV Whitespace</a> connections that some libraries are using.

That name may have a hard time catching up with '5G,' a tag that's been applied to just about every future mobile technology in the works: Googling '5G mobile' brings up 12.9 million results. But it's a clear sign of progress toward the concrete. Where there's a bureaucratic-sounding numeric acronym, can a formal standard be far behind? The ITU now has an answer to that question, too. It's set a <a href="http://www.itu.int/en/ITU-R/study-groups/rsg5/rwp5d/imt-2020/Pages/default.aspx" target="_blank">timeline</a> that calls for the standard to be finished in 2020. Hence the name, which follows in the footsteps of IMT-2000 (3G) and IMT-Advanced (4G)."</li>

Setting a standard will allow multiple devices, multiple networks and multiple users (humans/machines/drones/robots/phones/wearables) to access the network and its data in a consistent way, eliminating the need for humans to intervene. Additionally, allocation of more radio spectrum is vital to meet increased demand for capacity and data rates beyond 2020."</li>
<li style="text-align:justify;font-size:16px;font-family:arial;line-height:110%"><a href="https://www.fcc.gov/blog/leading-towards-next-generation-5g-mobile-services" target="_blank">Leading towards next generation "5G" mobile services</a> (Official FCC Blog | Tom Wheeler) "The NPRM [Notice of Proposed Rulemaking] will focus on developing a flexible regulatory framework that will allow maximum use of higher-frequency bands by a wide variety of providers, whether the service they provide is mobile, fixed, or satellite. I anticipate that we will explore a range of regulatory strategies depending on the specifics of each proposed higher-frequency band, including licensed, unlicensed, and hybrid shared models. In addition, as an implementation of existing flexible rules, I foresee lower-frequency bands playing a role in 5G. For example, the timing of the incentive auction makes the 600 MHz band a prime candidate for deployment of a wide-area 5G coverage layer. In much the same way that 700 MHz paved the way for America's world-leading deployment of 4G, so could 600 MHz accelerate U.S. deployment of 5G."</li>

One solution to the spectrum crunch could be to look beyond the lower-frequency spectrum - between 700MHz and 2.6GHz - used by most carriers today, and move towards higher spectrum bands such as 6GHz, 28GHz, and 38GHz. At the top end, beyond 30GHz, these extremely high frequency bands are known as millimetre wave. Bringing those bands into use is both one of the most exciting, and least guaranteed, areas of 5G development."</li>
